Tornadoes

At least two people were killed and six more injured as several tornadoes touched down in Texas and Mississippi on Saturday, damaging homes and flipping vehicles as the storm system moved east across Alabama early Sunday.

Millions of people from across the South are under threat of damaging winds, strong tornadoes and hail Saturday as the region braces for more potential destructive storms.

Also Saturday, San Francisco residents awoke to a tornado warning, but none touched down there. It was the first such warning for the city since at least 1950.
